Build cloud-native apps and microservices while running only what you need. Open LibertyTM is the most flexible server runtime available to JavaTM developers in this solar system.
Develop cloud-native Java microservices
Open Liberty is fast to start up with a low memory footprint and live reload for quick iteration. Simple to add and remove features from the latest versions of MicroProfile and Jakarta EE. Zero migration lets you focus on what's important, not the APIs changing under you.
